If your headlight is shown off, hyper flashing, bulb-out warning on the dashboard but actually work normally after LED replacement, it might be caused by a mismatch between the headlight bulb and car voltage/current. But don’t worry today we are disposed to solve this problem.
1.Install a decoder, this is for stabilization between the LED bulb and wire voltage/current.

2.Install a resistor, be sure to get the specialized technician’s help to install. This is for current enlargement to keep it stable with car voltage.

3.However, there are some executive cars such as VOLKSWAGEN, AUDI, BMW, and GMC that cannot use the above methods to deal with the problem. There is another means——correcting the ECU/driving computer error. Use OBD to read wrong messages on ECU and find professionals to fix it. Then you can use your once mistaken headlights normally.
